According to Albert Einstein's theory of relativity, all bodies in a vacuum regardless of their properties are accelerated by the Earth's gravity at the same rate. This principle of equiva-lence applies to stones, feathers and atoms alike. Under the conditions of microgravity very long and precise measurements can be carried out to determine whether different atoms of different mass actually "fall equally fast".
